General
The Service Software "PCLocals" is specially designed to facilitate the
servicing of GSM cellular telephones.

The software can be used to control the phone according to the user's
wish merely by entering commands via the keyboard of a PC/AT
connected to the phone.

This section refers to GSM PCLocals Version 1.0. To receive a free
upgrade, please follow the de­install instructions in Appendix I and send
the disk to Nokia Mobile Phones.

Required Servicing Equipment
­ Computer: IBM PC/AT or compatible with one unused serial port
(COM1 or COM2) *), one parallel port (LPT1), hard disk recommended
­ Operating System: DOS Version 3.2 or later
­ Display: Any 80­character text display
­ PCLocals program, 3.5" disk (product code: 0774028)
5.25" disk (product code: 0774031)
­ Software protection key PKD­1 (product code: 0750018)
­ M2BUS adapter DAU­2 (product code: 0750006)
­ Modular cable XCM­1 (product code: 4626131)
­ RS­232 adapter, 9­to­25 pins (product code: 4626170)
­ Service cable SCS­1 (product code: 0770010)
­ Service box JBS­7 (product code: 0770015)
­ Power connector PCS­1 (product code: 0730012)
­ Audio cable ADS­1 (product code: 0730011)
­ Mini UHF ­ BNC cable




*) Note: A number of PC's of an older generation use the Intel, National
Semiconductor, or United Microelectronics IC 8250 as the serial port UART.
This is a comparatively inefficient circuit for current purposes and does not
necessarily support the M2BUS adapter at 9600 baud. The newer UART's
NS16450 and NS16550AF of National Semiconductor offer solutions for
these problems.

Mechanical Connections
Caution: Make sure that you have switched off the PC and the printer
before making connections !
Caution: Do not connect the PKD­1 key to the serial port. You may
damage your PKD­1 !
The software controls the phone via a separate adapter connected to the
serial port of the PC and to the telephone's M2BUS (DAU­2 and XCM­1).
Attach the protection key PKD­1 to parallel port one (25­pin female
D­connector) of the PC. When connecting the PKD­1 to the parallel port
be sure that you insert the PC end of the PKD­1 to the PC (male side). If
you use a printer on parallel port one, place the PKD­1 between the PC
and your printer cable.
The PKD­1 should not effect devices working with it. If some errors occur
(errors in printing are possible) please try printing without the PKD­1. If
printing is OK without the PKD­1 please contact your dealer. We will offer
you a new PKD­1 in exchange for your old one.

Using Menus
All menu selections have a separate selection character in the first
column. This character is a number, a letter or a special ASCII character
(e.g., + or ­). Menus have a fixed constant display structure, i.e. the texts
cannot be scrolled.
You can select a function from a menu in two different ways. The first way
is to press the key on the PC keyboard corresponding to the first character
of the line. The other way is to move the cursor from line to line using
arrow keys and make the selection with the Enter key.
When you have made your selection the new menu or window will appear
on the PC screen. Every menu and window carries a name on the
topmost line. The name is the same as the selection in the previous menu
or window. When the new menu is activated the old one will disappear.
When a window is activated the selectable keys are seen in the window.
Windows may have a scrolling or a constant display.
Common control key symbols are always seen on the help line (line 25)
and the keys may be used always when seen on the last line.
With a window or menu active the Esc key is pressed to quit selection, put
out the window or menu and bring the previous menu or window to the
display. The Esc key doesn't have any effect when it is used with the main
menu. When editing data the Esc key can be used as interrupt key. During
edition the Enter key is used as exit key.
Help Functions

The last line (line 25) will always list the special keys which can be used.
The help key F1 can be used anytime when the menu is on the display.
When the help key is used a new window will appear on the screen. The
new window contains a text that describes the function over which the
cursor was when the help key was used. The Esc key will move the cursor
back to the menu and the help window will disappear.

P.A.M.S. NME­2A
Technical Documentation Service Software Instructions



Text Editing Windows

When you have made a selection which needs some additional
information, the basic text editing window is activated.
The text editing window may have one or more editing lines. The length of
the line varies depending on the function. When the window is activated
the text which was previously in that window (default text) reappears on
the screen.
The following key selections are possible:
Key Function

Enter Selects the text in the window; the editing window is turned off.
The selected text will be the default text of the selection.
Esc Interrupts editing; the previous menu is shown and the default
text won't be updated.
Ins Toggles the editing mode between insert and overstrike modes.
The last line of the screen tells the current editing mode. When
editing ends the editing mode is retained and same mode
is used again when editing text.
Arrow keys (right shift and left shift) move the cursor. The
cursor moves as if the lines were positioned one after another.
For instance right shift causes the cursor to move from the last
column of the first line to the first column of the second line. If
the right shift is used and the cursor is at the last position of
the last line, the cursor is not moved. Similarly, the cursor does
not move with the left shift key when it is at the first position of
the first line.
Home Moves the cursor to the start of the text.
End Moves the cursor to the end of the text.
BS The backspace key has two different meanings depending on
the editing mode;
· When the overstrike mode is activated the Backspace key
moves the cursor back and changes the character under the
cursor into a space. If the cursor is at the first position of the
first line nothing happens.
· When the insert mode is activated the Backspace key moves
the cursor back and deletes the character under the cursor so
that all characters after the deleted character are moved one
position back. If the cursor is at the first position of the first line
nothing happens.


Original 08/97 Page 13
NME­2A P.A.M.S.

Service Software Instructions Technical Documentation



Del Has also two different meanings depending on the editing
mode;
· When the overstrike mode is activated the Del key changes
the character under the cursor into a space and moves the
cursor for ward. If the cursor is at the last editing position of the
last line nothing happens.
· When the insert mode is activated the Del key removes the
character under the cursor so that all characters after the
removedcharacter are moved one position back. If the cursor
is at the last editing position of the last line nothing happens.
F1 Function key number 1 activates the help window.
F4 Clears text in the editing window.

PCLocals Menu Commands

When you start the PCLocals program, the main menu can be seen on the
screen. There are eight main functions;




The phone should be in the local mode for the third and fourth functions.
(After the program has started the phone automatically assumes the GSM
mode). You can change phone mode by choosing function "7 ­ Phone
mode".
The number identifier of each title refers to a main­ and a sub­menu item.
E.g., in 3.1.2 TX Power Level; the first number (3) refers to the third block
"3 ­ Testing and adjustment" of the main menu. The second number (1)
refers to the first block "1 ­ RF control" of the testing and adjustment
menu. The third number (2) refers to the second block "2 ­ TX power
level" of the RF control menu.

1 ­ PC Setup




When save setup is selected the basic text window is made and the
program asks setup file name. Enter the file name or use the default. Save
with the Enter key. The saved information includes all next selections (on
mentioned menus or windows) and parameters:
­ Command line parameter value for COM port selection
­ RF Controls menu

· All selections
­ Call Simulation

· All selections which are not same as in the RF Controls menu
­ Tuning parameters (PC default values; no effect on EEPROM
values)

· TX power coefficients
· Power connection diagram
­ Run MCU Self­tests

· All selections
Next selections are not saved to setup file:
­ Values which are asked from MS

· AFC value
­ Main Menu

· Phone Mode (Start value = Normal)




Page 16 Original 08/97
P.A.M.S. NME­2A
Technical Documentation Service Software Instructions



­ PC Setup menu

· Default name for setup file
(Start value = NME_2.CON)
­ Internal audio loop:

· input (Start value = Int)
· output (Start value = Int)
· loop (Start value = Off)
­ External audio loop:

· interface (Start value = HS)
­ Logic controls

· Car Radio Mute, CRM (Start value = Unmuted)
· LCD Test Display (Start value = 1)
Load function generates same kind of basic text window as save function
and asks setup file name. When the name has been give and Enter key
has been used the file is loaded and all previously told selections and
parameters are replaced with the values taken from the file. This has
same effect as command line parameter ­f.
Both save file and load file function has default name which is previously
used name. For instance if setup was saved to file CONF.CON and load
function is activated the default value is CONF.CON. If only Enter key is
pressed default value is used. If Esc key is used the function will be
interrupted. If invalid DOS filename is used or there isn't load file with
given name error message will come to the display.
If phone mode had Local value before setup file loading, the mode is
changed to Normal in the phone by special Normal mode message and all
functions caused by the change are done. If mode was Normal before
new setup, all needed setup file settings are sent to MS as in the previous
case, but phone mode change command is not sent to MS. Note next
exception: If phone mode is Normal and interface is M2BUS and
communication port is different in the setup file than the value before file
loading, then also Normal phone mode message has to be sent to MS.
Every time when phone mode change message from Local to Normal is
received by MS it makes reset to the whole MS.

Service Software Instructions Technical Documentation



2 ­ Initialize Phone
With this function you can initialize the phone to accept M2BUS
commands from the PC. This function should be used right after the
phone is connected to the PC and powered up.
The initialization function performs the following sub­functions:
­ MBUS registration
­ Test mode message sent to the phone
­ Phone mode set to GSM
­ AFC value removed from info window
3 ­ Testing and Adjustments




When testing and adjustment menu is selected, the phone mode must be
set to the "Local" value. If the local mode is not set, the error message is
shown.
Caused by the test interface slowness when M2BUS is used there may be
some delay between the user interface updating and the register controls
in the hardware.

This function changes the transmission data type. Every time when
selection is made the next value in the list is shown (i.e. 0/1/Random).
After random data selection 0 is used. If operating mode is continuous, TX
data type random causes different data sending than in burst mode.
3.1.5 ­ Continuous Mode Channel

Basic text editing window is used for giving continuous mode channel
number. Continuous mode may have all GSM channel numbers (GSM:
1...124). The used frequency depends on the active unit. If active unit is
RX, then RX frequency is used, else TX frequency.
3.1.6 ­ Channel; Monitoring Channel

Basic text editing windows are used for giving burst mode channel
numbers. "Channel" selection numbers are used for both transmission
and receiving. "Monitoring channel" is selected separately for neighbor
monitoring channel. All GSM channel numbers (in GSM phone: 1...124)
are valid.
3.1.7 ­ AGC

After this selection new window will be made and AGC value can be
edited in the basic text editing window. The AGC can have values (GSM:
0...93 dB) by 3 dB steps. If the number is not divisible evenly by 3 the
number is rounded to the next bigger number divisible by 3. Only the
number is edited (not letters dB).

3.2 ­ Adjustments




All adjustments which have EEPROM saving selection have the next kind
of behaving with F2 and Esc keys.
When adjustment function is activated and F2 key is used, the program
will ask whether the values should be saved to the EEPROM or not. If Y
key is used, adjustment values are saved to the EEPROM. If N or Esc key
is used the adjustment can be continued. If any other key is used nothing
happens.
When Esc key is used during adjustment function, the program will ask
whether the values should be saved to the EEPROM or not. If Y key is
used, adjustment values are saved to the EEPROM and exit from the
function is done. If N key is used exit is done from the function and
nothing is saved to the EEPROM. If Esc key is used the adjustment can
be continued. If any other key is used nothing happens. When exit is
made from the adjustment menu, the used adjustment values are used
with the normal DSP control commands in the local mode (i.e power
connection diagram and power levels).
3.2.1 ­ Continuous Mode Channel

Continuous mode channel number can be selected from Adjustments
menu. The real frequency (transmission or receiving frequency area)
depends on the Active Unit selection and the selected tuning function.
Active Unit defects to the frequency when no selection is made from the
Adjustments menu. Note that this is same selection as in the RF Controls
menu.

3.2.2 ­ TX Power Tuning (See updated version of PC Locals)

The next question is made to the user:
Values from EEPROM? (YES/NO) _

The user is also informed that TX power will be connected to lowest value
if he does not break the selection with Esc key.
If Y key is used, tuning values from EEPROM are loaded. If N key is
given, the values which PC program normally uses when DSP is
controlled are used. If Esc key is used the selection is interrupted and the
previous menu is shown on the screen. If any other key is used nothing
happens. PC program values are tuning settings which are used for DSP
control in the local mode.




The test power is selected automatically when the function is started. The
power is presented in GSM values (2...15) the test power is selected
automatically when the function is started. The test value is always same
when the function is started first time after PCLocals start­up. The test
value is not saved to the EEPROM. The test value can be changed during
tuning as other power coefficients and the program remembers its value
when tuning function is activated later again.
There is one selection which is used for power coefficient calculation. Only
three power levels are needed to tune (DA Step at power level 15 and
coefficients at level 10 and 2), the rest are calculated with F3.
The calculation is activated with F3 key. The power coefficients which are
calculated from the tuned coefficients are displayed on the different
columns than the others. All values can be tuned if needed.

Service Software Instructions Technical Documentation



The next automatic selections are made when this tuning function is
activated:
­ if transmission data is neither 0 nor 1 then continuous 1
data is selected
­ Active Unit = TX
­ the biggest power level is selected
­ Operation mode = Burst
­ Channel = 60
The cursor is shown on the tuning position. Next value is selected with
arrow keys.
+ and ­ keys will cause power changing by 0.25 dB steps (D/A converter
control value ratio is 1.0292). When these keys are used the coefficient
value is updated on the tuning window.
When save or exit selection is used, the power value checking is made
and if it is not succeeded, error message is shown. The test checks if all
power coefficient values are in the same order of magnitude as power
levels in the table.
When TX Power Tuning is ended and if the power values are not
acceptable, the error message is displayed and the user is asked to
continue or break the tuning. The next answers and responses are in use:
Key Response

N or Esc The tuning is continued
Y The tuning is ended without EEPROM writing and
power coefficients are asked from EEPROM (this is
also informed to a user)
other key ­
If the power tuning function is ended and EEPROM values are not
received or EEPROM fault is noticed, an error message is shown. Error
message asks to check M2BUS interface or set factory values. When any
key is pressed, adjustment menu is selected and PC values are used as
power coefficients, even though they have wrong values.

3.2.3 ­ TX Power Tuning (HW version 5.0 onwards)

From HW version 5.0 onwards a new way of compensating off­set values
on the transmitter control line has been implemented; this consists of a
D/A converter injecting an inverse offset voltage to cancel out initial offset.
The program automatically detects the HW version and shows controls for
the D/A converter if the HW version is 5.0 or higher.
In this case the screen will be as shown below.




At level 15 the actual step of the D/A is displayed. The count can range
from 0 to 63. The D/A converter can be controlled when positioning the
bar at power level 15.
Having the bar positioned at any other level causes the program to display
the D/A converter step only.




Original 08/97 Page 25
NME­2A P.A.M.S.

Service Software Instructions Technical Documentation



With the bar positioned at level 15, the following screen is shown.




Now F9 and F10 are used to control the D/A converter and subsequently
the feeding voltage (to cancel out the initial offset) is displayed.
Tuning for HW vesion 5.0 differs from the earlier versions as such:
The output power at level 15 MUST be tuned using the D/A converter; the
rest of the tuning remains the same.
If the TX Power Tuning is ended and power coefficients are acceptable,
the PC SW behaves as follows;
Key Response

Y The coefficients are written to EEPROM and tuning is
ended
N The tuning is ended without EEPROM writing but
the tuned coefficient values are used when RF
controls
are used
Esc The tuning is continued
other key ­
When all power coefficients have such values that they don't cause any
error messages, exit can be made. The last used tuning power is in use
after exit.
The next automatic selection is made when this tuning function is ended:
­ Active Unit = RX

3.2.4 ­ TX I/Q Tuning

This function is used for tuning TX I and Q branch DC offset, amplitude
difference and phase difference.
The function causes the same question about values (from EEPROM or
PC) as power tuning.
The next automatic selections are made when this function is activated:
­ Active Unit = TX
­ Operation Mode = Burst
­ TX Power Level = 10 (GSM)
­ If TX Data Type= RANDOM => TX Data Type= 1
­ Channel = 60 (GSM)
The next menu is displayed after the answer.




When one of the selection is made the menu will disappear from the
display and the control will be on the tuning window.
On the right top hand corner of the tuning window is shown what tuning is
activated. User can tune the current value with the plus + and minus ­
keys.
Tune TX I DC Offset
The DC Offset is shown as percentage (%) from the maximum value. 0 %
means that there is no DC. The value range is ­100 %...100 %. The value
is rounded to the nearest integer value. When this tuning is active the text
"I DC OFFSET TUNING" will be on the top right hand corner of the
display.

Tune TX I and Q DC Offset
The operation of this function is the same as one above, except with this
selection the both I and Q branch DC Offset is tuned. When plus + or
minus ­ ­key has pressed the both values are changed to the same
direction. If another value is in the limit value it does not change, but the
other value will change. When this tuning is active the text "I AND Q DC
OFFSET TUNING" will be on the top right hand corner of the display.
Tune Amplitude Difference
When this selection is made user can increase or decrease the amplitude
difference within 0.1 dB steps. The current amplitude difference is shown
on the tuning window with numbers and bar figure. When this tuning is
active the text "AMPLITUDE DIFFERENCE TUNING" will be on the top
right hand corner of the display.
Tune Phase Difference
When this selection is made user can increase or decrease the phase
difference within 0.5 steps. The current phase difference is shown on the
tuning window with numbers and bar figure. When this tuning is active the
text "PHASE DIFFERENCE TUNING" will be on the top right hand corner

3.2.7 ­ Noise Sensitivity

This function is used for making Signal to Noise measurement.
The next automatic selections are made when this tuning function is
activated:
­ Active Unit = RX
­ Operation mode = Continuous
­ AGC = 93 dB in GSM
When this selection is made the next window comes to the display.




Clipping Distance 30dB
SNR (AD converter) 16.5dB OUT OF RANGE
Sensitivity ­98.2dBm OUT OF RANGE
Si ­ Sq 1.2dB OUT OF RANGE

Clipping distance is the difference to the signal clipping value. SNR is
measured in A/D converter.
Clipping distance = clipping level (66) ­ signal value + comp_factor1 SNR
= signal value ­ noise value + comp_factor1
Sensitivity = ­92 dBm + 8 dB + comp_factor2 ­ SNR
The last value on the display is signal power difference between I and Q
branch. The numbers are shown in 0.1 dB accuracy. The error messages,
"OUT OF RANGE", are shown only if the SNR and/or amplitude difference
values are not acceptable
(SNR <= 18 dB + comp_factor2 ­ 0.5 dB(=accuracy) ;
Sensitivity >= ­102 dBm + 0.5 dB ; |Si ­ Sq| > 1dB).

When F2 or F3 key is pressed, the RX I and Q burst data is asked, text
"SIGNAL MEASURING" or "NOISE MEASURING" will come to the
measurement window and the next help line will come to the last line. The
power level value should be ­92 dBm during signal measurement.

Only Esc key is accepted during measurement. Esc breaks the
measurement routine in the PC and returns the program to the state
before F2 or F3 pressing. Normally Esc is not needed.

When signal data is received, distance to clipping signal level is shown as
dBs on the display. When either signal or noise measurement results are
received "MEASURING" text is removed and the first mentioned help line
is on the display. When both measurements (signal and noise) are done at
